Title: Filter press
IPC: B01D25/12
Filed: 1975-01-22
Abstract: 1486168 Filter press KUBOTA TEKKO KK (KUBOTA Ltd) 22 Jan 1975 [26 Nov 1974] 2855/75 Heading BID A filter press comprises plates 13, connected by links 16 which allow them to separate to a limited degree when the movable press head is withdrawn, an endless band of filter cloth 51 entrained round rolls (47) at the tops and bottoms of the plates so as to locate two vertical sections of cloth between each pair of adjacent plates, and nozzles 25 adapted to be clamped between adjacent plates when the press is closed and to deliver slurry into the spaces between the vertical cloth sections. The plates have recesses 20 with filtrate drainage channels 21 on one face and carry impervious diaphragms 22 inflated by water delivered via channels 46 to squeeze the filter cake on the other face. Channels 21 and similar channels on the outer faces of diaphragms 22 drain into passages 42 formed by aligned through holes in the plates. Fig. 4 shows how a nozzle 25 is shaped to fit within a recess 26 in the plate on one side. Nozzle 25 slides by means of rods 35 relative to that plate and is linked at 39 to the other adjacent plate, so that when the press opens nozzles 25 are separated from the plates on both sides. Nozzles 25 have passages 32 which cooperate with apertures 31 in lateral extensions 30 of the adjacent plates to define a slurry inlet channel when the press is closed, this channel opening into a delivery passage 33 in each nozzle. Extensions 30 and nozzles 25 may be duplicated on the other side of the press. After filtration the press is opened by ram (15), and the filter cloth band 51 is thereby stretched causing filter cake to fall therefrom. Drive roll (49) then moves the band through a cleaning station (65) including a brush and spray (Fig. 1, not shown). The band is rendered endless by a coupling (61) (Fig. 7, not shown), and a limit switch is provided opposite each roll 47 (Fig. 8 not shown) to ensure that the band stops with the coupling on a roll and not between two plates. The band is entrained round a further roll (53) whose axis can be variably inclined by a motor driven screw (Figs. 5, 6, not shown) to compensate automatically for any deviation from straight travel. Rolls (50) and (67) are relatively movable by ram (66') to stretch the band.

IPC: B29D30/28
Filed: 1958-01-29
Abstract: 908,118. Building pneumatic tyres. DUNLOP RUBBER CO. Ltd. Jan. 26, 1959 [Jan. 29, 1958; March 20, 1958], Nos. 2904/58 and 8890/58. Class 144 (1). The turn-down of the ply ends around the shoulders of a high crown building drum 1 is effected without puckering of the ply ends by first supporting the ply ends on cylindrical member 2 coaxial with the drum and applying a radially inwardly-directed force, as by a stretched rubber band or annular coil spring 5, or by an inflatable annulus 14, Fig. 7, around the junction of the drum 1 and support 2, and then removing the support 2 axially away from the drum, either slowly, in steps, quickly or with a reciprocating motion, to permit the force to effect ply turn-down. In alternative arrangements fluid pressure may be used as the turning force, or a stretched elastic strip 17, Fig. 9, applied to the inner or outer surface of the extremity of the ply end normally to hold the ply cords in position, may serve also as the ply-turning force. In the latter case the support 18 is withdrawn suddenly. In a further arrangement an inflatable bag may serve as the ply support deflation of which permits ply turn-down, and subsequent inflation of which, after positioning of a bead core, effects ply turn-up.

Abstract: 805,447. Protective cut-out arrangements. MECHANICAL PRODUCTS Inc. Jan. 30, 1956 [IFeb. 7, 1955], No. 2943/56. Class 38 (5) An overload circuit-breaker arrangement comprises moving contacts 44, 44<SP>1</SP> interconnected by a " thermostat metal " latch 40 which normally abuts a relatively fixed abutment 42 and is normally shunted by a switch having contacts 58, 58<SP>1</SP> carried by thermostat metal strips 54, 54<SP>1</SP>, the strip 54 being in the shunt circuit and the strip 54<SP>1</SP> providing ambient temperature compensation. The latch and the strips may be of bimetal or trimetal and the strips have their high expansion side facing adjusting screw 60. Under overload conditions, the strip 54 deflects to open the contacts 58, 58<SP>1</SP> so that the full current is caused to flow through the latch 40 which quickly separates from the abutment 42 and allows the springs 48 to open the contacts 44, 46 and 44<SP>1</SP> 46<SP>1</SP>. With the screw 60 in the full line position it restrains the outward movement of the strip 54<SP>1</SP> so that ambient temperature compensation is provided above a normal temperature and release is delayed for temperatures below normal, but with the screw in the dotted position it merely functions to maintain the desired contact pressure.
